$15K–$90K typical projects
Claude API Development for startups, scale-ups, and agencies that need a senior engineer — not a dev shop. I ship production React Native apps and the Python + AI systems behind them: FastAPI, RAG, LLM integrations, and agent workflows.
You need an MVP or v2 shipped on budget with someone who makes architecture decisions and owns delivery end-to-end.
You need a senior IC to augment the team, rescue a codebase, or lead mobile + AI integration without months of hiring.
You need a reliable senior subcontractor for client projects — clear communication, store-ready quality, white-label friendly.
